CVE-2026-23062: platform/x86: hp-bioscfg: Fix kernel panic in GET_INSTANCE_ID macro

MediumCVSS 5.5 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.14% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 193922a23d7294085a47d7719fdb7d66ad0a236f, 25150715e0b049b99df664daf05dab12f41c3e13, eb5ff1025c92117d5d1cc728bcfa294abe484da1.

Low priority for now. Upgrade to Linux Linux 193922a23d7294085a47d7719fdb7d66ad0a236f, 25150715e0b049b99df664daf05dab12f41c3e13, eb5ff1025c92117d5d1cc728bcfa294abe484da1 or later.

In the Linux kernel, the following vulnerability has been resolved: platform/x86: hp-bioscfg: Fix kernel panic in GET_INSTANCE_ID macro The GET_INSTANCE_ID macro that caused a kernel panic when accessing sysfs attributes: 1. Off-by-one error: The loop condition used '<=' instead of '<', causing access beyond array bounds. Since array indices are 0-based and go from 0 to instances_count-1, the loop should use '<'. 2. Missing NULL check: The code dereferenced attr_name_kobj->name without checking if attr_name_kobj was NULL, causing a null pointer dereference in min_length_show() and other attribute show functions. The panic occurred when fwupd tried to read BIOS configuration attributes: Oops: general protection fault [#1] SMP KASAN NOPTI KASAN: null-ptr-deref in range [0x0000000000000000-0x0000000000000007] RIP: 0010:min_length_show+0xcf/0x1d0 [hp_bioscfg] Add a NULL check for attr_name_kobj before dereferencing and corrects the loop boundary to match the pattern used elsewhere in the driver.
